The cross talk occurring between bifidobacteria in the mammalian’s gut microbiota [ATCC15697]

ABSTRACT: We describe the molecular cross talk established under in vivo conditions between a set of human gut bifidobacterial commensals. Eleven groups of five conventional female 8-wk-old BALB/c mice taking a standard polysaccharide-rich Chow diet were administered a single daily dose of 109 CFU of either B. bifidum PRL2010, B. breve 12L , B. adolescentis 22L , B. longum subsp. infantis ATCC15697, or bifidobacterial couples, i.e., PRL2010-12L, PRL2010-22L, PRL2010-ATCC15696, 12L-22L, 12L-ATCC15697, 22L-ATCC15697, or a combination of all bifidobacterial strains. The transcriptome of bifidobacterial strains under in vivo conditions was analyzed. The transcripts expressed in B. bifidum PRL2010, B. breve 12L, B. adolescentis 22L and B. longum subsp. infantis ATCC15697 were profiled using a custom-made PRL2010-12L-22L-ATCC15697 (multibifido)-array representing 100%, 99%, 96%, 99% of the identified genes of these organisms, respectively.The observed functional changes in the trascriptomes of bifidobacteria might be caused by the possible shifts of the mice cecum microbiota upon colonization with bifidobacteria. Thus, we assessed if the presence of B. bifidum PRL2010, B. breve 12L, B. adolescentis 22L and B. longum subsp. infantis ATCC15697 on mono-, bi- or multi-association in the cecum of mice affects the overall composition of the microbiota of this environment.

The cross talk occurring between bifidobacteria in the mammalian’s gut microbiota [22L]

Bifidobacterium breve UCC2003 metabolizes lacto-N-tetraose and lacto-N-neo-tetraose through overlapping, yet distinct pathways

Project description:Recent studies have begun to elucidate the mechanisms of utilisation of some human milk oligosaccharides (HMO) components by Bifidobacterium breve. However, this phenomenon is still relatively poorly understood, with little to no work to date in understanding a number of specific structures common to HMO. In this study, we demonstrate that the prototype B. breve strain UCC2003 possesses specific metabolic pathways for the utilisation of Lacto-N-Tetraose and Lacto-N-neoTetraose, which represent the central moieties of Type I and Type II HMOs, respectively. Using a combination of experimental approaches, the enzymatic machinery involved in the metabolism of these two HMO structures was identified and characterised. Homologs of tWe also identified the key genetic loci involved in the utilisation of these HMO substrates in B. breve, B. bifidum and B. longum subsp. infantis using bioinformatic analyses were shown to be, and noted the relatively variably present among other members ofscant distribution of their homologs across the Bifidobacterium genus as a whole, withwhile noting a distinct pattern of conservation of LNB utilisation genes inamong human-associated bifidobacterial species.

Molecular response of bifidobacteria to a cholesterol rich environment

Project description:We investigated the capabilities of bifidobacteria to reduce the cholesterol level in the media, which clearly evidenced a high ratio of assimilation of this molecule by specific bifidobacterial strains including Bifidobacterium bifidum PRL2010. The transcriptomics of PRL2010 cells cultivated in the presence of cholesterol evidenced a significant higher expression of carriers as well as reductase encoding genes

RNA sequencing of CACO-2 cells incubated with Bifidobacteria breve grown on human milk oligosaccharides.

Project description:Background: Breastfed human infants are predominantly colonized by bifidobacteria that thrive on human milk oligosaccharides (HMO). The two most predominant species of bifidobacteria in infant feces are Bifidobacterium breve (B. breve) and Bifidobacterium longum subsp. infantis (B. infantis), both avid HMO-consumer strains. Our laboratory has previously shown that B. infantis, when grown on HMO, increase adhesion to intestinal cells and increase the expression of the anti-inflammatory cytokine interleukin-10. The purpose of the current study was to investigate the effects of carbon source—glucose, lactose, or HMO—on the ability of B. breve and B. infantis to adhere to and affect the transcription of intestinal epithelial cells on a genome-wide basis. Results: HMO-grown B. infantis had higher percent binding to Caco-2 cell monolayers compared to B. infantis grown on glucose or lactose. B. breve had low adhesive ability regardless of carbon source. Despite differential binding ability, both HMO-grown strains significantly differentially affected the Caco-2 transcriptome compared to their glucose or lactose grown controls. HMO-grown B. breve and B. infantis both down-regulated genes in Caco-2 cells associated with chemokine activity. Conclusion: The choice of carbon source affects the interaction of bifidobacteria with intestinal epithelial cells. HMO-grown bifidobacteria reduce markers of inflammation, compared to glucose or lactose-grown bifidobacteria. In the future, the design of preventative or therapeutic probiotic supplements may need to include appropriately chosen prebiotics.

Carbohydrate Syntrophy enhances the establishment of Bifidobacterium breve UCC2003 in the neonatal gut

Project description:To extend our understanding of bifidobacterial mutualism and carbohydrate syntrophy in the gut we adopted advanced functional genomics to create single- and double-deletion isogenic strains of the NagA encoding genes of B. breve UCC2003. The resulting strains were examined, as compared to the parent strain, for their ability to metabolise particular host derived carbohydrates. In addition, the B. breve strains were examined for their crossfeeding capability and ability to establish, in the presence of B. bifidum ATCC29521, in the gut of dam fed neonatal mice.

Transcriptional response to protease treatments (kallikrein, papain and chymotrypsin) of Bifidobacterium breve 210B

Project description:Members of the serpin (serine protease inhibitor) superfamily have been identified in higher, multicellular eukaryotes, as well as in bacteria, although surveillance of available genome sequences indicates that bacterial serpin-encoding (ser) homologs are not widely distributed. In members of the genus Bifidobacterium this gene appears to be present in at least five, and perhaps up to nine, out of 30 species tested. Moreover, phylogenetic analysis using available bacterial and eukaryotic serpin sequences revealed that bifidobacteria specify serpins that form a separate clade. We characterized the ser210B locus of Bifidobacterium breve 210B, which consists of a number of genes, whose deduced protein products display significant similarity to proteins encoded by corresponding loci found in several other bifidobacteria. Northern hybridization, primer extension, micro array analysis, RT-PCR and Quantitative Real Time (qRT) - PCR analysis revealed that a 3.5 kb polycistronic mRNA, encompassing the ser210B operon with a single transcriptional start site, is strongly induced following treatment of B. breve 210B cultures with particular proteases. In contrast, transcription of the ser homolog of other bifidobacteria, such as Bifidobacterium longum subsp. infantis, Bifidobacterium dentium and B. longum subsp. longum, appears to be triggered by a different set of proteases Transcriptional response to protease treatments (kallikrein, papain and chymotrypsin) of Bifidobacterium breve 210B
